Ho paka ho paka le thepa ea ho tiisa mocheso ke tse latelang;

1. Mokhoa oa ho paka oa ho paka

Mekhoa ea ho tiisa liphutheloana e kenyelletsa ho tiisa ho chesang, ho tiisa ho bata, ho tiisa sekhomaretsi, jj. Ho tiisoa ha mocheso ho bolela tšebeliso ea karoloana e kahare ea lera la thermoplastic mohahong oa filimi o nang le likarolo tse ngata, o nolofatsang ho tiisa ha o futhumatsa le ho tiisa ha mohloli oa mocheso o tlosoa. Lisebelisoa tsa ho tiisa mocheso, ho roala le ho qhibiliha ho chesang ke lintho tse sebelisoang haholo ho tiisa mocheso. Ho tiisa ho bata ho bolela hore e ka tiisoa ka ho tobetsa ntle le ho futhumatsa. Seaparo se tloaelehileng sa ho tiisa se batang ke seaparo se bohale se sebelisitsoeng bohale ba mokotla oa ho paka. Ho tiisa sekhomaretsi ha se sebelisoe hangata ka har'a mekotla ea lintho tse ngata, e sebelisoa feela bakeng sa ho paka thepa e nang le pampiri.

2. Mocheso oa ho tiisa mocheso

(1)Polyethylene (PE) ke mofuta oa boka bo bosoeu bo bosoeu, bo fetohang ebile bo le lerootho. Ha e na tatso, ha e na chefo ebile e bobebe ho feta metsi. PE e nang le li-macromolecular chain e na le maemo a bonolo ebile e bonolo ho e khabisa. Ke sesebelisoa se thata mochesong oa kamore. Joaloka thepa ea ho paka, bothata bo ka sehloohong ba PE ke ho thatafala ha moea, ho kenella ho phahameng ho khase le mouoane oa tlhaho, matla a tlase le ho hanyetsa mocheso; ho bonolo ho nyenyefatsoa ke khanya, mocheso le palo, ka hona, antioxidant le khanya le mocheso o tsitsisang hangata li eketsoa lihlahisoa tsa PE ho thibela botsofali; PE e na le khatello e mpe ea khatello ea tikoloho, ebile ha e hane le ts'enyeho ea h2s04, HNO3 le oxidant ea eona, 'me e tla senyeha ke li-hydrocarbon tse ling tsa aliphatic kapa li-hydrocarbon tsa chlorine ha li futhumetse; ts'ebetso ea khatiso ea PE e futsanehile, 'me bokaholimo ha bo na polar, kahoo kalafo ea corona e tlameha ho etsoa pele ho hatisoa le ho hokahana ho omileng ho ntlafatsa kamano le khokahano e ommeng ea enke ea khatiso.

PE e sebelisetsoang ho tiisa litheko ka mocheso e kenyelletsa:
Poly tlaase segokanyipalo nhua polyethylene (LDPE), tsejoang hape e le phahameng khatello ea nhua polyethylene;
② phahameng segokanyipalo nhua polyethylene (HI) PE, tsejoang hape e le tlaase khatello ea nhua polyethylene;
③ polyethylene e mahareng (nu) PE :); linear low density polyethylene (LLDPE);
Loc metallocene catalyzed nhua polyethylene.

(2)Thepa ea filimi ea polypropylene (CPP) e sebelisetsoang ho tiisa thepa e futhumetse e batla e fapane hanyane le ea polypropylene e nang le biaxial ka lebaka la ts'ebetso ea eona e fapaneng ea tlhahiso. Melemo le likotsi tsa CPP li bonts'oa ka har'a litaba tsa "polypropylene".

(3) PVC (e khutsufalitsoeng joaloka PVC) ke lehoakhoa le se nang 'mala, le bonaletsang le le thata le nang le matla a limolek'hule tse ngata le matla a matla a limolek'hule, kahoo e na le thatafalo e ntle le botlolo ea polasetiki e thata.

PVC e theko e tlaase ebile e tenyetseha haholoanyane. E ka etsoa ka lijana tse thata tsa ho paka, li-bubble tse bonaletsang le lifilimi tse kenang habonolo le thepa ea polasetiki ea foam. Ka lebaka la chefo ea eona le ho bola ha eona, ts'ebeliso ea eona ea fokotseha mme butle-butle e nkeloa sebaka ke lisebelisoa tse ling.

(4) Eva (ethylene vinyl acetate copolymer) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) ( Eva) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (eva-eva) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (Eva. ke copolymerization ea asene ea ethylene le vinylacetic asiti ea eona e fetoha le litaba tsa monomers tse peli.Ka hona, ha ho khethoa mofuta oa EVA, e lokela ho khethoa ho latela ts'ebeliso, mme e ka sebelisoa e le polasetiki, sekhomaretsi se chesang le ho roala .
Eva e sebelisoa haholo joalo ka karolo e kahare ea filimi e nang le likarolo tse ngata ka lebaka la ho tiea ha eona hantle le matla a tlase a ho tiisa mocheso. E sebelisoa ho likhomaretsi, ho roala, ho roala, ho kenya mohala oa cable le sesebelisoa sa 'mala ka ho khomarela ha eona hantle (ho chesa hantle kapa ho itseng ka lisebelisoa tse ngata tsa polar le tse seng tsa polar).

(5)PVDC (polyvinylidene chloride) PVDC ka kakaretso e bua ka copolymer ea vinylidene chloride. Polima e fumanoang ka ho fetofshoa e na le khanya e phahameng ea khanya, sebaka se phahameng sa ho nolofatsa (185-200'c) mme e haufi le mocheso oa ho bola (210-2250). E na le tšebelisano e mpe le sesebelisoa se akaretsang, kahoo ho thata ho bōptjoa.
PVDC ke thepa e matla ebile e bonaletsang e nang le khanya e hodimo le botala bo bosehla. E na le sekhahla sa phetisetso e tlase haholo ho khase ea metsi e metsang, khase le monko, 'me e na le khanyetso e ntle ea mongobo, ho tiisa moea le ho boloka monko o monate. Ke lisebelisoa tse ntle tse thibelang moeli o phahameng haholo. E hanyetsana le asiti, alkali le li-solvents tse fapaneng, e hanela oli, e hanyetsa ebile e tima.
